In terms of priority and possibility of success/
1.EU should fund major studies on biofuels-in cooperation with USA and China. All interested sides face energy problems and both USA and China are having good progress in research on gene modification. EU could use its good relations with both sides to act as mediator and help to stabilise world relations. Not only would EU benefit directly in terms of research and potential energy sources, but its role as international mediator would increase. The large amounts of agricultural land in EU that has to be funded by CAP could be turned into something usefull.
2. Fund research related to solar energy such as solar power satellites and solar towers. Thus should be done with cooperation of USA (NASA) and ESA. Currently both NASA and ESA are engaging in ambitious projects such Orion and Aurora. NASA is interested in going into Moon which has been hinted as possible source of material for solar cells for SPS. Cooperation in such matter would increase trans-atlantic ties also. EU should also make treaties creating a status of EU partner countries that would have closer ties to EU and potential membership and adress them to countries such as Algeria and Morroco. Which are less populated and ideal candidates for Solar Towers or receiving stations for SPS.
3. Increase international cooperation on ITER.
All those attempts would be more creative and potentially beneficial to EU then surrendering to Russia. Sadly I doubt such visions exist in EU as it lacks the spirit and sould of creativity and Germany is determined to pursue alliance with Russia at all costs, and would likely block attempts to stop Russian dependency.
